Codeigniter搜索栏

Question

Searchbar正在codeigniter网站上工作，但它不会加载建议产品。正如我想要的，如果有人在searchbay中写'戴尔'，他应该得到戴尔笔记本电脑的建议如下。另一件事“输入”按钮不适用于搜索，必须单击搜索图标才能搜索product.code，如下所示 控制器

function text_search(){
    if ($this->crud_model->get_settings_value('general_settings','vendor_system') !== 'ok') {
        $search = $this->input->post('query');
        $category = $this->input->post('category');
        redirect(base_url() . 'index.php/home/category/'.$category.'/0-0/0/0/'.$search, 'refresh');
    }else{
        $type = $this->input->post('type');
        $search = $this->input->post('query');
        $category = $this->input->post('category');
        if($type == 'vendor'){
            redirect(base_url() . 'index.php/home/store_locator/'.$search, 'refresh');
        } else if($type == 'product'){
            redirect(base_url() . 'index.php/home/category/'.$category.'/0-0/0/0/'.$search, 'refresh');
        }
    }
}

模型

function get_type_name_by_id($type, $type_id = '', $field = 'name')
{
    if ($type_id != '') {
        $l = $this->db->get_where($type, array(
            $type . '_id' => $type_id
        ));
        $n = $l->num_rows();
        if ($n > 0) {
            return $l->row()->$field;
        }
    }
}
function get_settings_value($type, $type_name = '', $field = 'value')
{
    if ($type_name != '') {
        return $this->db->get_where($type, array('type' => $type_name))->row()->$field;
    }
}
